信息再生装置及信息再生方法 Apparatus and information reproduction method for reproducing information

技术领域 FIELD

[0001] 本发明涉及对适用了逻辑覆写(overwrite)的信息记录介质进行再生的信息再生装置及信息再生方法、对适用了逻辑覆写的信息记录介质进行记录再生的信息记录再生装置及信息记录再生方法。 [0001] The present invention relates to an information recording medium applied to logical overwrite (Overwrite) of the information reproducing apparatus and an information reproducing method for reproducing, an information recording medium applied to logical overwrite of the information recording and reproducing apparatus reproducing information recording and reproducing method.

背景技术 Background technique

[0002]近年来,BD-RE (Blu-ray Disc Rewritable)及BD_R(Blu_ray Disc Recordable)这样的、大容量的可改写型光盘、追记型光盘得到了普及。 [0002] In recent years, BD-RE (Blu-ray Disc Rewritable) and BD_R (Blu_ray Disc Recordable) such that the large-capacity rewritable optical disc, write once optical disc has been popular. 在BD之中的作为追记型光盘的BD-R也采用缺陷管理系统,将缺陷块向设置于内周和外周的备用区域交替记录,由此来确保数据记录的可靠性。 As write once optical disc BD-R is also used in the BD defect management system, to record the defect blocks are alternately disposed in the inner periphery and the outer periphery of the spare area, thereby to ensure the reliability of data recording. 进而,如果对已记录区域受理了数据记录请求,则通过向用户数据区域的未记录部分交替记录,来实现逻辑覆写(或虚拟覆写)。 Furthermore, if the accepted data recorded area on the recording request, through an unrecorded portion of the user data area are alternately recorded to implement logical overwrite (or virtual override).

[0003] 在图13中示出二层BD-R的逻辑构造(参照非专利文献I)。 [0003] Layer shows the logical configuration of BD-R in FIG. 13 (refer to Non-Patent Document I). 给BD-R分配了:用于记录用户数据的用户数据区域、用于交替记录用户数据区域的缺陷块的备用区域、用于记录盘管理信息的DMA (Disc Management Area)以及TDMA (Temporary Disc ManagementArea)。 Assigned to the BD-R: a user data area for recording user data, a spare area for alternatively recording a defective block of the user data area, a DMA (Disc Management Area) for recording disc management information and a TDMA (Temporary Disc ManagementArea ). 其中,TDMA也被称为暂时管理信息区域。 Which, TDMA is also known as the temporary management information area.

[0004] 在使盘结束之前将盘管理信息记录至TDMA,在使盘结束时将盘管理信息记录至DMA。 [0004] The disc management information recorded in the TDMA to the plate prior to the end, when the end of the disc when the disc management information is recorded to the DMA.

[0005]如图 14 所不,对TDMA 追记记录了多个TDMS(Temporary Disc ManagementStructure)(参照专利文献I)。 [0005] FIG. 14 is not, additional recording of a plurality of TDMA TDMS (Temporary Disc ManagementStructure) (refer to Patent Document I). 在盘的记录模式为时序记录模式(Sequential RecordingMode)的情况下,TDMS 中包括TDFL (Temporary Defect List)、SRRI (Sequential RecordingRange Information)以及TDDS (Temporary Disc Definition Structure)。 In the case of the recording mode, the recording mode is a timing disc (Sequential RecordingMode) of, TDMS includes TDFL (Temporary Defect List), SRRI (Sequential RecordingRange Information) and a TDDS (Temporary Disc Definition Structure). TDFL 主要被用作对与盘上的缺陷区域相应的交替区域进行管理的缺陷列表。 TDFL is mainly used as the defect management spare area corresponding to the defect list area on the disc. SRRI中主要包括被称为SRR(Sequential Recording Range)的与记录区域相应的管理信息。 The SRRI including referred SRR (Sequential Recording Range) corresponding to the management information recording area. TDDS中包括TDFL、SRRI的配置信息或备用区域的容量等的盘的定义构造信息。 The TDDS information of the disc structure including definitions TDFL, the SRRI configuration information capacity of spare area or the like. 其中,TDMS也被称为暂时管理信息,TDFL也被称为(暂时)缺陷列表。 Which, TDMS is also known as temporary management information, TDFL is also known as (temporary) defect list.

[0006] 使用图15来说明逻辑覆写的动作。 [0006] FIG 15 will be described in the logical overwrite operation. 如果以在块P中记录有数据A的状态而在块P中覆写数据A',则在未记录区域起始的块Q记录数据A',并且将缺陷列表作为TDFL具备的TDMS追记记录于TDMA,其中缺陷列表追加了表示从块P向块Q交替记录的入口(entry)。 If P is recorded in the data block A of the state data is overwritten in block P A ', the region is not the start of the record data A recording block Q', and a defect list TDFL included in the TDMS write-once recorded TDMA, wherein the defect list is additionally recorded from the block represented by P alternately to the inlet block Q (entry). 之后,如果对块P受理再生请求,则在参照缺陷列表而确认出从块P向块Q交替记录之后,再生块Q而得到数据A'。 Thereafter, if the block P receives a regeneration request, then confirm from the recorded alternately after the block P to block Q, Q to obtain reproduction data block A 'with reference to the defect list. 通过这样进行使用了缺陷列表的交替记录来实现逻辑覆写。 Used to implement defect alternate logical overwrite recording performed by such a list.

[0007] 使用图16来说明下述情况:如果采用这种逻辑覆写,则在覆写了文件的情况下无法取得进行覆写之前的内容。 [0007] FIG 16 will be described below: If the logical overwrite With this, the content can not be obtained before overwriting in the case where the file is overwritten. 在图16中,FE (File Entry)是包括文件的属性、记录了文件内容的位置、尺寸等的信息在内的元数据。 In FIG. 16, FE (File Entry) is a file attribute, the metadata information recording location, file size, etc. including contents. 物理记录内容是在盘上实际被记录的内容,逻辑记录内容是从反映了逻辑覆写结果的信息记录再生装置外能够参照的内容。 Physical content recorded content on the disc is actually recorded, a logical record content from an outer logical overwrite results reflect information recording and reproduction apparatus can refer to the content. 如图16(a)所示为记录有File-A和FiIe-B的状态,如图16(b)所示用File_A'对File-A进行了覆写的情况下,在将File-A'的内容记录于未记录区域之后,用File-A'的FE对File-A的FE进行逻辑覆写。 FIG 16 (a) shows a state where the recording File-A and FiIe-B of FIG. 16 (b) shown by File_A 'File-A to the case where the overwrite is performed in the File-A' after the contents recorded in an unrecorded area, with FE File-a 'FE File-a to be logical overwrite. 其结果,如图16(b)所示,无法从信息记录再生装置外参照File-A的FE,作为结果而记录了File-A内容的位置、尺寸变得不明了,因而无法取得File-A的内容。 As a result, as shown in FIG 16 (b), the outside can not be referred to from the information recording reproducing apparatus FE File-A as a result of recording the File-A content location, size becomes unclear, and therefore can not obtain File-A Content.

[0008] 与之相对,在专利文献2中公开了在覆写了文件的情况下取得进行覆写之前的内容的方法。 [0008] On the other hand, Patent Document 2 discloses a method for obtaining content in a case where before overwriting the file overwritten. 在专利文献2中,在DDS(TDDS)包括恢复DLT (TDFL)地址的构成中,通过以恢复DLT(TDFL)为源而返回到以前的DLT(TDFL)来恢复过去的状态。 In Patent Document 2, in the DDS (TDDS) including recovery DLT configuration (the TDFL) addresses, to recover by DLT (the TDFL) is returned to the previous source DLT (the TDFL) to restore the previous state.
